There are also other issues with your used cfg:
May 26 12:12:09 dev-proxy05 kamailio[5098]: ERROR: <core> [db.c:466]: db_check_table_version(): invalid version 4 for table uacreg found, expected 5 (check table structure and table "version") May 26 12:12:09 dev-proxy05 kamailio[5098]: ERROR: uac [uac_reg.c:1382]: uac_reg_load_db(): Error during version check for db table: uacreg, check database structure.
As recommeded from @miconda - please try to reproduce it with a minimal cfg.
